The processing unit performs operations comprising: performing spatial filtering over the Q audio signals using a trained model based on an arc line with a vertical distance and a horizontal distance from a midpoint between the first and the second microphones, a time delay range for the first and the second microphones and coordinates of the Q microphones to generate a beamformed output signal originated from zero or more target sound sources inside a target beam area, where Q>=3.

Abstract: A tie includes an RFID device and a body encapsulating the RFID device by overmolding. The body includes a strap member, a head member, and a protection member connected between the strap member and the head member. The strap member has a plurality of engaging teeth. The RFID device is embedded in the protection member. The head member has a through hole. A hole wall of the through hole is provided with a one-way pawl. When winding the body around an object, the protection member can get a better protection since the protection member is located on an inner side between the head member and the strap member without protruding outward. Because the protection member and the head member are closer to a surface of the object, the extent to which the protection member protrudes outwards is reduced, thereby facilitating the RFID device to be sensed more easily.
